FEED-CUTTER.

SPECIFICATION forming part of Letters Patent No. 611,335, dated September 27, 1898.

Application filed March 1'7, 1897. Serial No. 628,008. (No model.)

To .ctZZ whom it may concern:

Be it known that I, J OAOHIM SCHILDHAUER,

object being to. so construct the apparatus that the material will be positively and uni= formly fed to the knives and then cut on a transverse line oblique to the line of feed.

With these and other objects in view the invention consists in the several details of construction and combination of parts herein after fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of the machine. Fig. 2 is a plan view. Fig. 3 is a side elevation, partly in section, looking at the machine from the opposite side to that shown in Fig. 1. Fig. 4 is a vertical longitudinal section. Fig. 5 is a vertical transverse section. Fig. 6 is a perspective detail of the follower used in this machine, Fig. 7 is a detail in elevation of the hand-lever at the inner end of the longitudinal shaft, showing the locking-pin for holding this lever in position to connect the cutting mechanism with the feeding mechanism.

Similar reference-numerals indicate similar parts in the several figures.

1 represents the feeding-box, supported at its rear end on a trestle 2. The front end of the box is cut obliquely on a transverse line, as indicated at 3, and this end of the feeding-box is supported on the rear end of the frame a, which extends obliquely to and in advance of the sides'of the feeding box.

A shaft 6 extends transversely below the feeding-box and is journaled insuitable bearings 7 on plates 8, supportedby brackets 9, bolted to the opposite sides of the feedingbox. The bottom of the feeding-box is cut away, as indicated at 10, to admit the lower feed-rolls, (indicated, respectively, by 11 and 12.) The roll 11 is rigidly mounted on the shaft 6, and the spindle 13 of the roll 12 is journaled in suitable bearings 14., also supported on the plates 8. Theshaft 6 also oarries a sprocket-wheel 15, and 'thespin'dle 13 rolls.

carries a similar sprocket-wheel 16, and over these two sprocket-wheels a sprocket-chain 17 runs to impart uniform movement to the The upper rolls are indicated by 18 and 19 and theirspindles by 20 and 21, respectively. These spindles are supported in slotted openings 22, formed in the sides of the feeding-box. The spindles 20 and 21 project beyond their hearings on both sides of the frame, and on the front side of the feedingbox eachcarries a sprocket-wheel 23, over which sprocket-wheels a sprocket-chain 24 runs for the purpose of transmitting movement from one to the other. The opposite end of the spindle21 is also provided with a sprocket-wheel 25, and the end of the shaft 6 on this side of the machine carries a sprocketwheel 26.

27 and 28 represent sprocket-wheels mounted on a counter-shaft 29, which shaft is sup ported at one end in the side of the feedingbox and at its other end in a bracket 30, secured to the feeding-box. 31 represents. an endless sprocket-chain which runs from the sprocket-wheel 26 on the shaft 6 under and over the sprocket-wheel 27,

thence under and overthe sprocket-wheel 25 on the spindle of the roll 19,'thence over and under the sprocket-wheel 28 back to the sprocket-wheel 26 on the shaft 6. By this arrangement the upper rolls 18 and 19are driven directly from the shaft 6, as are also the lower rolls 11 and 12 but the upper rolls move in a reverse direction to the lower rolls, and all the rolls are positively and uniformly driven, thereby insuring a positive and uniform feed of the material to theknives.

33 represents hangers, one of the hangers depending from each end of the spindles 20 and 21. The lower ends of each pair of hangers on opposite sides of the feed-box are loosely connected bya bowed stirrup-bar 34, and the two stirrups 34: are loosely connected at their centers by a bar 35, extending transversely beneath the feeding-box.

36 represents a lever connected at one end to a stirrupor strap 37, secured to the frame 4E, and this lever is supported intermediate its IOO The weighted lever 36 tends to hold the upper rolls 18 and 19 down onto the material, but permits a yielding vertical movement when necessary. From the construction described it will be clear that either upper roll can rise and fall independently of the other and at either end or both ends, as may be necessary from the size and shape of the obstruction passing beneath it.

39 represents the main driving-shaft jour naled in suitable bearings 40, secured on the top of the frame 4, and this shaft carries a cutter-cylinder having spirally-arranged knives 41. The knives are so arranged as to cut the material on an oblique line correspondin g to the obliquity of the front end 3 of the feed-box, the out commencing at the point nearest the rolls and where the latter have the strongest grasp on the feed or stalks, whereby lateral slipping is prevented.

42 represents a longitudinal shaft journaled at one end in a bearing 43, supported on an extension 44 of the frame 4. The other end of this shaft 42 is journaled in a suitable hearing attached to a lever 45, and this lever is pivoted at its lower end on an extension 46 of the trestle 2. The lever 45 may be locked in position by a locking-pin 47, passing through the lever into the extension 46 and which may readily be removed for the purpose of rocking the lever when necessary.

The shaft 6 is provided with a beveled gear 48, which engages a beveled gear 49, rigidly supported on the shaft 42. The driving-shaft 39 is also provided with a beveled gear 50, which meshes with a beveled gear 51 on the end of the shaft 42. By this arrangement of gearing movement is transmitted from the driving-shaft 39 to the shaft 42 through the medium of the beveled gears 50,and 51 and from the shaft 42 to the shaft 6 through the medium of the beveled gears 49 and 48, and the feed-roll are thereby given a uniform 'rotary movement which will have a uniform ratio to the rotary movement of the cuttingblades. When it is desired to stop the revolution of the feed-roll without stopping the movement of the cutting-blades, the locking-pin 47 can be removed, and by rocking the lever 45 on its pivot, as seen in dotted lines in Fig. 7, the beveled gear 49 will be disengaged from the gear 48 and thereby stop the movement of the feed-rolls, while the knives may continue their movement, if desired.

52 represents a follower arranged in the front end of the feed-box in proximity to and in advance of the feed-rolls. The forward end of this follower is cut obliquely to correspond with the oblique end of the feed-box, as indicated at 53. The follower is provided with vertical guide-plates 54, which engage slots 55 directly opposite each other in the desired; but, as best seen in Fig. 4, they extend downward only a sufficient distance to permit the follower to descend to a horizontal line about flush with the lower sides of the upper rolls in their normal position, thus avoiding the striking of the feed against the front edge of the follower after it passes between the rolls. This follower is weighted, but is free to have vertical movement should such movement be necessary in the operation of the machine. I consider the use of this follower highly important in connection with the transverse rolls, because after the ends of any straw have passed from between the rolls they are held by the follower steadily in position to be cut by the knife, and this would not be the case if the follower were of different shape.

The driving-shaft 39 is provided at one end with fastand loose pulleys 32, through which power may be transmitted to the shaft in the usual manner. At its opposite end it is provided with a fly-wheel 56 in the usualmanner, to which may be attached a handle 57 to operate the machine by manual power.

The operation of the machine will be readily understood from the foregoing description, and it will be seen that the mechanism hereinbefore described will insure a positive and uniform feed of the material to the knives and that it will be cut on a transverse line oblique to the line of feed. This makes the cutting much easier, and consequently relieves the knives of unnecessary strain,thereby increasing the period of their usefulness and avoiding frequent repairs.

It will be understood that changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim is 1. In a feed-cutter, the combination with the box and its feedrolls, one of them having a bevel-gear on its shaft, a trestle for supporting the rear end of the box, a main driveshaft journaled in a frame which supports the front end of the box, the cutting mechanism on this shaft, and a bevel wheel also thereon; of extensions from the sides of the box, a bearing carried by the forward extension, a longitudinal shaft journaled therein and having bevel-gears oneof which is in constant mesh with that on the driving-shaft and the other of which is adapted to be thrown into or out of mesh with that on the feed-roll, a hand-lever pivoted to the other extension and having a bearing supporting the remote end of the longitudinal shaft, and a locking-pin removably passing through this bearing parallel with the shaft and into the extension, as and for the purpose set forth.
